Good starting points
Not presets: three places to start, then trust your ears.
Dreamy: 80% and a hall
The classic sound. Slow enough to feel heavy, still easy to follow.
Soft: 90% and a room
Close to the original, just warmer. Good for vocals you want to keep clear.
Very slow: 70% and a wide hall
Deep and washed out. Best on simple songs with few instruments.
Slowed + reverb, nightcore or daycore?

Questions about slowed + reverb
Will a slowed song get a copyright claim?
A slowed version is still the same song, so posting someone else’s music can get a claim. Slow a song you made yourself, or make one here with AI first and slow that.
What is the best speed?
Most slowed songs sit between 80% and 90%. Start at 85% and move it until the voice still sounds natural to you.
Does the pitch go down too?
Yes, on purpose: like a record played slower, the pitch drops with the speed. To change only the pitch, use the Pitch Shifter.
Can I save it as an MP3?
It saves a WAV file. Convert it to MP3 afterwards with any converter if you need a smaller file.
Is my song uploaded?
No. The song is changed in your browser and never sent to us.
How slow can it go?
Down to 70% of the original speed. At 80% a 2:30 song lasts about 3:08; at 70% it lasts about 3:34.
Which song can I try slowed + reverb on?
Load Windows Down, the summer pop song in the example above, from the button under the drop zone. At 80% with a hall reverb its 2:30 runs to about 3:08.
Can I make a sped-up or nightcore version here?
This page only slows songs down. For sped-up, open the Pitch Shifter, set the speed up to 150% and raise the pitch a few steps.
